Specification of Letters Patent.

Patented Jan. 8,190'2 Application filed June 25,1906. Serial No, 323,2110.

T0 @ZZ whom/ it may concern:

Be it known. that I, LEMUEL B. S'rEvENs, a citizen of the ll nited States, and a resident oi liogansport, in the county o' Cass and State oi indiana, have invented a new and linproved illilking-Machine, oi which the iollowing is a full, clear, and exact description.

llfhis invention relates to improvements in machines for milking cows, the object being to provide a ldevice i'or hat will this purpose t be siinplc in construction, inexpensive, and easily operated.

l will describe a milking-machine embodying iii inventiony and then point out the novel-features in the appended claims.

ll eiercnce is to be had to the accompanying drawings, forming a part of this specification, .in which. similar characters of reference indicate corresponding parts in all the figures.

Figure l is an elevation, partly in section, oi a inilking-niachine cinbodying iny invention. Fig. 2 is a plan'thereo'f, and Fig. 3 is sectional detail showing an adjusting ineclianisni employed.

1n carrying out iny invention l eniploy a unip comp-rising a cylinder 1,*in which a piston 2 operates, the *aid piston having an opening which is closed on the downward niovenicnt ot the piston by ineans oi a valve 3, here shown as a Hap-valve. The stein 4 oi' the piston extends downward through the bottoni wall of the cylinder and connects with a lever 5, pivotally connected to a hanger 6, attached to the pump-cylinder. The cylinder is supported by ineans oY a rod 7 adjusti ble vertically in a tubular support S, designed to engage with the grounr or iioor. The rod 7 is provided with a plurality oi notches 9, in any one of which a pawl 10 inay engage for holding the punip as adjusted vertically. This pawl l() is inovable through a slot 11 in the tubular support and is pivoted. to a bracket 12, secured to said tubular support.

The tubular support 8 has a swinging connection in a substantially horizontal plane with a seat 13. ils here shown, this connection consists ci a rod or tube 11i, attached to a coupling 15 on the part 8 and also attached to a T-'iitting 16, having swinging connection with the forward portion oi the vseat and with a hanger 17 attached to the seat. B y this ineans the punip and th l parts carriedtliereby inaybe swung laterally with relation to the seat.

l niittiiig the Communicating with the upper portion ci the cylinder l are branch pipes 1S, and each branch pipe has a exible tube or pipe connection 19 with a coat-receiver 20, inade in the forni of a cup and preierably oi" ilexible material. V

Communicating with the lower portion of the pump-cylinder is a discharge-tube 21, ci' rubber or like ilexible material, for conducting the niilk to a pail or bucket, (indicated by the dotted lines 22 in Fig. 1,) the said. pail or bucket being supported on a shelf 23, attached to the legs ci the stool or seat.

1n the opera tion a person sitting on the seat or stool by inoving the lever 5 downward will obviously cause a downward nioveincnt oi' the piston, und as the valves carried thereby will be close l the inilk. will be drawn lroin the udder, and tnen upon an. upward inovcnient oiY the piston the valve will open, perinilk to pass to the under side ci' the piston, and then by a subsequent downward iiiovcinent the niilk underneath the iston will be Jforced through the pipe 21 and at the saine time a fresh supply of niilk will be drawn.

llaving thus described iny invention, claiin as new and desire to secure by Letters Patent l. A. nullnng--inachinc comprising a pump, teat-eups coinniunicating with the upper portion thcreol", a lever l'or operating the puinppiston, a vertically-adiustable support for the puinp, a stool with which said support has connection, and a discharge-pipe loading freni the lower portion of the pump-cylinder.

2. A inilking-inachiiie comprising a puinp` .inps having ilexilile lube connection with theupperportion ol' lhepuinp-cylindcna lever for operating the pump-piston, a support i'oi' the pu nip, consisting oi' tubular ineniber, and a toothed rod movable inthe tubular nien ibcr, a pawl pivoted to the tubular ini'rnibe;l and adapted to engage with any one oi the teeth, a rod having` connection with said tubular ineinber, e seat with which the 'rod has swinging connection, and discbarge-tubsy ading froin the lower portion oiz the puinp.

3. A niilking-nimfliine'comprising a pcinpcylinder, a piston der, and having an opening, a valve'loi said opening, tent-cups having ilexible tubo connection with the upper portionoi the punipcylinder, a4 stein extended downward 'fi-oni the' pist-on through the bottom wall of the 1n testimony whereof l have signed my (luder, a lever with which said stem conmairie to this specilication in lthe preseneeof its, a support for the pump, a seat, a eon- I two subscribing witnesses.
